알루미늄청동 아크 용사층의 성질에 미치는 용사 공정변수 및 후열처리 영향
Effect of process parameter and post heat treatment on the properties of aluminium bronze arc spray coating
초록
In this study, as an effort to improve the brittlement of coating layer, aluminum bronze coatings formed on steel substrates by arc jet spray process were subjected to post heat treatment. After each treatment, mechanical properties such as hardness, and UTS, and microstructural characterization of the specimens were investigated. The results showed that the hardness in the coatings slightly decreased with increasing heat treatment tine and temperature. The UTS of as-sprayed coatings was 4.31kgf/
